Abstract: A method of controlling a battery charger to charge a battery includes setting a fan speed threshold for a fan within a battery charger, wherein the fan speed threshold is less than a maximum fan speed of the fan. The operating speed of the fan in the battery charger is controlled so as not to exceed the fan speed threshold and the battery charger is controlled to deliver a first charge current such that a temperature of the battery charger does not exceed a first temperature threshold while the operating speed of the fan remains at or below the fan speed threshold. A user input is received to engage a fast charge mode and, in response thereto, the operating speed of the fan is increased above the fan speed threshold so as not to exceed the maximum fan speed.

Abstract: A waterproof marine power supply system is provided. The system includes an enclosure defining an interior region and including an upper wall and a lower wall, a first peripheral wall and a second peripheral wall, and a convection passage wall extending within the interior region and separating a convection passage from a component space, where the convection passage extends from a first end to a second end of the enclosure. The component space houses power supply components. The system further includes a first end cap, a second end cap, and a fan coupled to either the first end cap or the second end cap and configured to force a flow of air through the convection passage. The first end cap and the second end cap are coupled to the enclosure such that the component space is sealed against water intrusion and the convection passage is not sealed against water intrusion.

Abstract: A chassis for an electronic device is provided. The chassis extends in a longitudinal direction and is defined in a lateral direction perpendicular to the longitudinal direction. The chassis includes a bottom surface extending in the longitudinal direction, and multiple fins projecting downwardly from the bottom surface and extending in the longitudinal direction. The chassis further includes a slot extending in the lateral direction through the fins so as to allow air to flow along the chassis in the longitudinal direction in between the fins and in the lateral direction through the first slot.

Abstract: A vehicle electrical control system for a vehicle includes a first battery having a first nominal voltage and a second battery having a second nominal voltage that is lower than the first nominal voltage. A single battery management system is electrically connected to both the first and second batteries. Both the first and second batteries are referenced to a single ground terminal. The first battery may be a starting battery and the second battery may be a house battery.

Abstract: A charger for a battery comprises a charger housing, a charging circuit within the charger housing, and a charger cable mechanically connected to the charger housing and electrically connected to the charging circuit. A connector is provided on a free end of the charger cable. The connector comprises a body, an electrical terminal supported by the body, and a fuse electrically connected between the charging circuit and the electrical terminal. The fuse is located at least partially within the body of the connector.

Abstract: A marine battery charger cable extender includes a terminal end that has a positive extender ring terminal and a negative extender ring terminal, and a connection end configured to connect to a terminal end of a pre-wired battery charger. The connection end includes a positive ring end, a positive ring connector configured to hold the positive ring end and galvanic connection with a positive ring terminal of the pre-wired battery charger, and a positive connection cover configured to completely encapsulate the connected positive ring end of the cable extender and the positive ring terminal of the pre-wired battery charger.

Abstract: A marine battery charger system configured to be installed on a marine vessel to charge a marine battery includes a housing, a charging circuit in the housing configured to receive AC power and to output a charge current to the marine battery, and a cord. The cord has a plug end configured to engage an AC power outlet and is configured to transmit the AC power from the AC power outlet to the charging circuit. A controller is configured to control a charging operation mode of the charging circuit and a status indicator is located at the plug end of the cord and configured to be controlled by the controller to indicate the charging operation mode of the charging circuit.

Abstract: A plug holder for installing a male plug end of a marine battery charger on a marine vessel includes an outer housing, a removable sleeve, and a backstop. The outer housing has a front end defining a plug opening and a back end defining a back opening, wherein the outer housing is attachable to a vessel hull and configured to hold a male plug end of the marine battery charger within the outer housing such that it is accessible through the plug opening. The removable sleeve fits within the outer housing and is shaped to secure the male plug end within such that it does not move when connecting or disconnecting thereto. The backstop is removably connectable to the back end of the outer housing to cover the back opening. The backstop is configured to retain the removable sleeve and the male plug end within the outer housing.
